Definitions
- the invention relates to an outside mirror according to the preamble of claim 1 (see e.g. DE-A-2 239 853).
- Such exterior mirrors are pivotally attached to a bearing block which is attached to the driver's cab of a commercial vehicle via holding arms. To maneuver or in particular to park the commercial vehicle, these exterior mirrors often have to be adjusted by pivoting the holding arm appropriately around the bearing block. They must also meet the requirement to move fully forward or backward when the mirror hits an obstacle. Here again, it is disadvantageous that precisely defined positions of the holding arm relative to the driver's cab cannot be easily restored.
- the invention is therefore based on the object to design a holder of the generic type so that on the one hand a complete evasion of the mirror is ensured when it hits an obstacle, but on the other hand defined positions of the holding arm and thus the mirror should be easily adjustable.
- the measures according to the invention ensure that the holding arm can only be adjusted relative to the bearing block between two defined stop positions against a frictional torque.
- These two stop positions can relate, for example, to the normal driving position and a parking position in which the mirror is pivotally pivoted in the direction of the driver's cab. If the mirror hits an obstacle, it can be pivoted beyond the stop positions by releasing the elastic snap-in connection. Swiveling back leads to the locking connection being closed again, which then makes it possible to pivot between two defined stop positions.
- this primarily affects trucks and buses, but also other vehicles.
- the measures according to claim 2 create a simple releasable snap connection.
- the development according to claim 3 specifies how, on the one hand, the defined stop positions are created and, on the other hand, the release of the latching connection is made possible.
- Claim 4 specifies a structurally simple configuration for this.
- Claim 5 specifies an elegant constructive solution for the arrangement of the locking connection in the bearing block.
- the configuration according to claim 7 creates particularly good frictional relationships between the holding arm and the bearing block, the further configuration according to claim 8 indicating how the friction torque can be adjusted.
- Claim 9 gives further details of the design of the latching connection.
- FIG. 1 shows a rearview mirror, which is an exterior rearview mirror for a commercial vehicle.
- This has a housing 1, in which a mirror pane 2 is held by means of a holding frame 3.
- a double-arm holding arm 4 is attached to the housing 1 so that it can pivot about an axis 5 by means of a clamping piece 6.
- the holding arm 4 is pivotally mounted on a bearing block 7, which in turn can be attached to the cab of the commercial vehicle. It rests with a contact surface 8 on the driver's cab, not shown, and is fastened there by means of screws which are screwed into threaded holes 9 of the bearing block 7.
- the double-armed holding arm 4 consists of an upper holding arm 10 and a lower holding arm 11, which are assigned or facing one another in pairs. At their end facing the housing 1, they each have one Pivots 12, 13, which are aligned with one another and are concentric with the axis 5 and which are held on the housing 1 by means of the clamping piece 6. At their ends attached to the bearing block 7, they are provided with articulated parts 14, 15 which are pivotably mounted on the bearing block 7 in a manner to be described in more detail about a pivot axis 16.
- the pivot axis 16 and the axis 5 run parallel to one another, ie the two holding arms 10, 11 are located in a common plane which is spanned by the axis 5 and the pivot axis 16.
- the bearing block 7 has a cylindrical inner space 17 which runs concentrically to the pivot axis 16 and which is closed off from the joint part 15 of the lower holding arm 11 by a wall section 18 of the bearing block 7. To the hinge part 14 of the upper holding arm 1o, this interior is closed off by a locking disk 19 which is axially fixed against an annular collar 2o on the interior 17 in the direction thereof and which is rotatably fixed relative to the pivot axis 16 by means of a tongue-and-groove connection 21 the bearing block 7 is connected.
- the interior 17 is penetrated concentrically to the pivot axis 16 by a bolt 22 which is received in the joint part 14 of the upper holding arm 10 and is connected to it in a rotationally fixed manner by means of a pin 23 relative to the pivot axis 16.
- the bolt 22 passes through the joint part 15 of the lower holding arm 11.
- This joint part 15 is braced against the bearing block 7 by means of a nut 25 screwed onto a threaded section 24 of the bolt 22.
- friction disks 26, 27 are arranged in each case, which provide for generating a sufficiently high frictional force between the holding arm 4 and the bearing block 7.
- the level of this frictional force is determined by a correspondingly strong one Tightening the nut 25 on the threaded portion 24 of the bolt 22 is determined, which is not only non-rotatably connected to the upper joint part 14 by the pin 23, but also in the direction of the pivot axis 16.
- a prestressed helical compression spring 28 which surrounds the bolt 22 and is supported against the lower wall section 18 and on which an end facing away from the wall section 18 is arranged a support disk 29 which is freely displaceable in the interior 17 and on the bolt 22.
- a locking sleeve 3o is arranged on the bolt 22, which is pressed firmly against the locking disc 19 due to the prestress of the compression spring 28 and is clamped between the latter and the support disc 29 as it were.
- the locking sleeve 3o has on its side adjacent to the locking disc 19 a locking recess 31 into which a locking projection 32 formed on the facing side of the locking disc 19 projects.
- the projection 32 and the recess 31 have flanks 33, 34 which are strongly inclined relative to the direction of the pivot axis 16, so that when the locking sleeve 3o is rotated relative to the locking disc 19 about the pivot axis 16 the disc 19 and the sleeve 3o are pressed apart in the direction of the pivot axis 16.
- the locking sleeve 3o has a cutout 35 on its side adjacent to the support disk 29.
- This cutout 35 is penetrated by a stop pin 36 which - as can be seen in FIG. 3 - penetrates the bolt 22 perpendicular to the pivot axis 16 and whose length corresponds approximately to the diameter of the interior 17.
- This stop pin 36 is thus non-rotatably connected to the bolt 22, thus rotates with it in the event of corresponding pivoting relative to the bearing block 7 about the pivot axis 16.
- the cutout 35 is such that the two ends of the stop pin projecting from the pin 22 are associated with stop surfaces 37, 38 on the latching sleeve 3o.
- the holding arm 4 can be pivoted relative to the bearing block 7 about the pivot axis 16 by an angle a, with this pivoting movement only having to overcome the friction torque generated on the friction disks 26, 27.
- the holding arm 4 with the mirror is pivoted between two defined positions, in which either the stop surface 37 or the stop surface 38 abuts the stop pin 36.
- These two defined relative positions of the holding arm 4 with mirror relative to the bearing block 7 and thus to the cab of the commercial vehicle can, for example, a driving position, i.e. define the normal operating position of the mirror and the parking or washing position, in which the mirror is partially pivoted towards the cab.
- the possible Stroke c of the locking sleeve 3o on the bolt 22, that is, the possible displacement path of the locking sleeve 3o on the bolt 22 in the direction of the pivot axis 16 is greater than the height d of the locking projection 32 relative to the locking disc 19 in the direction of the pivot axis 16.
- the holding arms 10, 11 are hollow, in particular the lower holding arm 11 is designed such that an electrical cable (not shown) can be guided through it, which is invisible into the housing 1 through the pivot pin 13 to the outside to be led.

Description
Die Erfindung betrifft einen Außenspiegel nach dem Oberbegriff des Anspruches 1 (siehe z.B. DE-A-2 239 853).The invention relates to an outside mirror according to the preamble of claim 1 (see e.g. DE-A-2 239 853).
Derartige Außenspiegel sind über Haltearme an einem Lagerbock schwenkbar angebracht, der am Führerhaus eines Nutzfahrzeuges angebracht wird. Diese Außenspiegel müssen zum Rangieren oder insbesondere zum Parken des Nutzfahrzeuges oft durch entsprechendes Verschwenken des Haltearms um den Lagerbock verstellt werden. Außerdem müssen sie die Forderung erfüllen, beim Auftreffen des Spiegels auf ein Hindernis vollständig nach vorn oder hinten auszuweichen. Hierbei ist es wiederum von Nachteil, daß exakt definierte Stellungen des Haltearms relativ zum Führerhaus nicht in einfacher Weise wieder herstellbar sind.Such exterior mirrors are pivotally attached to a bearing block which is attached to the driver's cab of a commercial vehicle via holding arms. To maneuver or in particular to park the commercial vehicle, these exterior mirrors often have to be adjusted by pivoting the holding arm appropriately around the bearing block. They must also meet the requirement to move fully forward or backward when the mirror hits an obstacle. Here again, it is disadvantageous that precisely defined positions of the holding arm relative to the driver's cab cannot be easily restored.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Halterung der gattungsgemäßen Art so auszugestalten, daß einerseits ein vollständiges Ausweichen des Spiegels bei dessen Auftreffen auf ein Hindernis sichergestellt ist, wobei andererseits aber definierte Positionen des Haltearms und damit des Spiegels leicht einstellbar sein sollen.The invention is therefore based on the object to design a holder of the generic type so that on the one hand a complete evasion of the mirror is ensured when it hits an obstacle, but on the other hand defined positions of the holding arm and thus the mirror should be easily adjustable.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale im Kennzeichnungsteil des Anspruches 1 gelöst. Durch die erfindungsgemäßen Maßnahmen wird erreicht, daß der Haltearm gegenüber dem Lagerbock zwischen zwei definierten Anschlagpositionen nur gegen ein Reibmoment verstellbar ist. Diese beiden Anschlagpositionen können beispielsweise die normale Fahrstellung und eine Parkstellung betreffen, in der der Spiegel schützend in Richtung zum Führerhaus hin verschwenkt wird. Trifft der Spiegel auf ein Hindernis, so kann er unter Lösen der elastischen Rastverbindung über die Anschlagpositionen hinaus verschwenkt werden. Ein Rückschwenken führt dazu, daß die Rastverbindung wieder geschlossen wird, wodurch dann das geschilderte Verschwenken zwischen zwei definierten Anschlagpositionen möglich ist. Wenn in diesem Zusammenhang von Nutzfahrzeugen die Rede ist, dann betrifft dies primär Lastkraftwagen und Omnibusse, aber auch weitere Fahrzeuge.This object is achieved by the features in the characterizing part of
Durch die Maßnahmen nach Anspruch 2 wird eine einfache lösbare Rastverbindung geschaffen. Die Weiterbildung nach Anspruch 3 gibt an, wie einerseits die definierten Anschlagpositionen geschaffen und andererseits das Lösen der Rastverbindung ermöglicht wird. Anspruch 4 gibt eine konstruktiv einfache Ausgestaltung hierfür an.The measures according to
Anspruch 5 gibt eine elegante konstruktive Lösung für die Anordnung der Rastverbindung im Lagerbock an.
Durch die Weiterbildung nach Anspruch 6 werden weitere konstruktive Einzelheiten hierzu angegeben.The further development according to claim 6 further structural details are given.
Durch die Ausgestaltung nach Anspruch 7 werden besonders gute Reibverhältnisse zwischen Haltearm und Lagerbock geschaffen, wobei die weitere Ausgestaltung nach Anspruch 8 angibt, wie das Reibmoment einstellbar ist.The configuration according to
Anspruch 9 gibt weitere Einzelheiten der Ausgestaltung der Rastverbindung an.

In Fig. 1 ist ein Rückblickspiegel dargestellt, bei dem es sich um einen Außen-Rückblickspiegel für ein Nutzfahrzeug handelt. Dieser weist ein Gehäuse 1 auf, in dem eine Spiegelscheibe 2 mittels eines Halterahmens 3 gehalten ist. Am Gehäuse 1 ist ein doppelarmiger Haltearm 4 um eine Achse 5 schwenkbar mittels eines Klemmstücks 6 angebracht.1 shows a rearview mirror, which is an exterior rearview mirror for a commercial vehicle. This has a
An seinem anderen Ende ist der Haltearm 4 an einem Lagerbock 7 schwenkbar angebracht, der wiederum am Führerhaus des Nutzfahrzeuges anbringbar ist. Er liegt mit einer Anlagefläche 8 an dem nicht dargestellten Führerhaus an und wird dort mittels Schrauben befestigt, die in Gewindelöcher 9 des Lagerbocks 7 eingeschraubt werden.At its other end, the holding arm 4 is pivotally mounted on a
Der doppelarmige Haltearm 4 besteht aus einem oberen Haltearm 1o und einem unteren Haltearm 11, die einander paarweise zugeordnet bzw. zugewandt sind. An ihrem dem Gehäuse 1 zugewandten Ende weisen sie jeweils einen Schwenkzapfen 12,13 auf, die miteinander fluchten und zur Achse 5 konzentrisch sind und die mittels des Klemmstücks 6 am Gehäuse 1 gehalten werden. An ihren am Lagerbock 7 angebrachten Enden sind sie mit Gelenkteilen 14,15 versehen, die am Lagerbock 7 in noch genauer zu beschreibender Weise um eine Schwenkachse 16 schwenkbar angebracht sind. Die Schwenkachse 16 und die Achse 5 verlaufen parallel zueinander, d.h. die beiden Haltearme 1o,11 befinden sich in einer gemeinsamen Ebene, die durch die Achse 5 und die Schwenkachse 16 aufgespannt wird.The double-armed holding arm 4 consists of an
Der Lagerbock 7 weist einen konzentrisch zur Schwenkachse 16 verlaufenden zylindrischen Innenraum 17 auf, der zum Gelenkteil 15 des unteren Haltearms 11 durch einen Wandabschnitt 18 des Lagerbocks 7 abgeschlossen ist. Zum Gelenkteil 14 des oberen Haltearms 1o ist dieser Innenraum durch eine Rast-Scheibe 19 abgeschlossen, die gegen einen Ringbund 2o am Innenraum 17 axial in Richtung auf diesen hin festgelegt ist und die mittels einer Nut-Paßfeder-Verbindung 21 relativ zur Schwenkachse 16 drehfest mit dem Lagerbock 7 verbunden ist. Der Innenraum 17 wird konzentrisch zur Schwenkachse 16 von einem Bolzen 22 durchsetzt, der in dem Gelenkteil 14 des oberen Haltearms 1o aufgenommen und mit diesem mittels eines Stiftes 23 relativ zur Schwenkachse 16 drehfest verbunden ist. Der Bolzen 22 durchsetzt den Gelenkteil 15 des unteren Haltearms 11. Dieser Gelenkteil 15 ist mittels einer auf einen Gewindeabschnitt 24 des Bolzens 22 aufgeschraubten Mutter 25 gegen den Lagerbock 7 verspannt. Zwischen dem Gelenkteil 14 und der Rast-Scheibe 19 einerseits und zwischen dem Wandabschnitt 18 und dem unteren Gelenkteil 15 andererseits sind jeweils Reib-Scheiben 26,27 angeordnet, die zur Erzeugung einer ausreichend hohen Reibungskraft zwischen dem Haltearm 4 und dem Lagerbock 7 sorgen. Die Höhe dieser Reibungskraft wird durch entsprechend starkes Anziehen der Mutter 25 auf dem Gewindeabschnitt 24 des Bolzens 22 bestimmt, der mit dem oberen Gelenkteil 14 durch den Stift 23 nicht nur drehfest, sondern auch in Richtung der Schwenkachse 16 fest verbunden ist.The
Im Innenraum 17 ist eine den Bolzen 22 umgebende, sich gegen den unteren Wandabschnitt 18 abstützende vorgespannte Schrauben-Druckfeder 28 angeordnet, auf derem dem Wandabschnitt 18 abgewandten Ende eine Stützscheibe 29 angeordnet ist, die im Innenraum 17 und auf dem Bolzen 22 frei verschiebbar ist.Arranged in the
Zwischen der Rast-Scheibe 19 und der Stützscheibe 29 ist auf dem Bolzen 22 eine Rast-Hülse 3o angeordnet, die aufgrund der Vorspannung der Druckfeder 28 fest gegen die Rast-Scheibe 19 gedrückt wird und zwischen dieser und der Stützscheibe 29 gleichsam eingespannt ist. Die Rast-Hülse 3o weist an ihrer der Rast-Scheibe 19 benachbarten Seite eine Rast-Ausnehmung 31 auf, in die ein an der zugewandten Seite der Rast-Scheibe 19 ausgebildeter Rast-Vorsprung 32 hineinragt. Der Vorsprung 32 und die Ausnehmung 31 weisen - wie Fig. 2 erkennen läßt - relativ zur Richtung der Schwenkachse 16 stark geneigte Flanken 33,34 auf, so daß bei einer Verdrehung der Rast-Hülse 3o gegenüber der Rast-Scheibe 19 um die Schwenkachse 16 die Scheibe 19 und die Hülse 3o in Richtung der Schwenkachse 16 auseinandergedrückt werden.Between the
Die Rast-Hülse 3o weist auf ihrer der Stützscheibe 29 benachbarten Seite einen Ausschnitt 35 auf. Dieser Ausschnitt 35 wird von einem Anschlag-Stift 36 durchsetzt, der - wie Fig. 3 erkennen läßt - den Bolzen 22 senkrecht zur Schwenkachse 16 durchsetzt und dessen Länge etwa dem Durchmesser des Innenraums 17 entspricht. Dieser Anschlag-Stift 36 ist also drehfest mit dem Bolzen 22 verbunden, dreht sich also mit diesem bei entsprechenden Verschwenkungen relativ zum Lagerbock 7 um die Schwenkachse 16. Der Ausschnitt 35 ist derart, daß den beiden aus dem Bolzen 22 herausragenden Enden des Anschlag-Stiftes 36 Anschlagflächen 37,38 an der Rast-Hülse 3o zugeordnet sind.The locking sleeve 3o has a
Wie ebenfalls Fig. 3 entnehmbar ist, kann der Haltearm 4 relativ zum Lagerbock 7 um die Schwenkachse 16 um einen Winkel a verschwenkt werden, wobei bei dieser Schwenkbewegung nur das an den Reib-Scheiben 26,27 erzeugte Reibmoment zu überwinden ist. Der Haltearm 4 mit dem Spiegel wird hierbei zwischen zwei definierten Stellungen verschwenkt, in denen entweder die Anschlagfläche 37 oder die Anschlagfläche 38 am Anschlag-Stift 36 anliegt. Diese beiden definierten Relativstellungen des Haltearms 4 mit Spiegel relativ zum Lagerbock 7 und damit zum Führerhaus des Nutzfahrzeugeas können beispielsweise eine Fahrstellung, d.h. die normale Betriebsstellung des Spiegels und die Park- oder Waschstellung definieren, in der der Spiegel teilweise an das Führerhaus herangeschwenkt ist.As can also be seen in FIG. 3, the holding arm 4 can be pivoted relative to the
Wenn der Haltearm in einer der beiden möglichen Richtungen über diese Anschlagstellung, d.h. über den Winkel a hinaus verschwenkt wird, dann nimmt der an einer der Anschlagflächen 37 oder 38 anliegende Anschlag-Stift die Rast-Hülse 3o mit und verdreht diese relativ zur Rast-Scheibe 19, wodurch der Rast-Vorsprung 32 aus der Rast-Ausnehmung 31 über die Flanken 33 oder 34 herausgedreht wird. Hierbei wird dann die Rast-Hülse 3o gegen die Kraft der Schrauben-Druckfeder 28 in Richtung zur Druckfeder 28 hin verschoben. Eine Verschwenkung des Haltearms zum Führerhaus hin durch die Anlage des Haltearms 4 am Führerhaus begrenzt, ist also nicht spezifisch für die Ausgestaltung des Haltearms 4 mit Lagerbock 7. Der mögliche Hub c der RastHülse 3o auf dem Bolzen 22, also der mögliche Verschiebeweg der Rast-Hülse 3o auf dem Bolzen 22 in Richtung der Schwenkachse 16 ist größer als die Höhe d des Rast-Vorsprungs 32 gegenüber der RastScheibe 19 in Richtung der Schwenkachse 16. Bei der Anlage des als Mitnehmer dienenden Anschlag-Stiftes 36 an der Anschlagfläche 37 nimmt der Haltearm 4 eine definierte Anschlagposition 39 ein, während er bei der Anlage des Anschlag-Stiftes 36 an der Anschlagfläche 38 eine definierte Anschlagposition 4o einnimmt. Die beiden Anschlagpositionen 39,4o definieren zwei Anschlagpositionen, in denen der Haltearm 4 relativ zum Lagerbock 7 spielfrei gehalten wird. In einer Richtung liegt er formschlüssig gegen die entsprechende Anschlagfläche 37,38 an. In der anderen Richtung ist er durch das entsprechende Reibmoment gehalten.If the holding arm is pivoted in one of the two possible directions beyond this stop position, ie beyond the angle α, then the stop pin bearing against one of the
Wie Fig. 2 entnehmbar ist, sind die Haltearme 1o,11 hohl ausgebildet, wobei insbesondere der untere Haltearm 11 so ausgebildet ist, daß durch ihn ein nicht dargestelltes elektrisches Kabel geführt werden kann, das durch den Schwenkzapfen 13 nach außen unsichtbar in das Gehäuse 1 geführt wird.As can be seen in FIG. 2, the holding
